To all whom it may concern:

Be it known that I, SAMUEL P. BRICKER, a citizen of the United States,residing at Allegheny, in the county of Allegheny and State ofPennsylvania, have invented certain new and useful Improvements in MetalWeather- Strips, of which the following is a specification, referencebeing had therein to the accompanyingdrawings, forming a part of thespecification, inwhich Figure 1 is a perspective view of one end of myim roved strip. Fig. 2 is a cross-section throng a window-frame andeasing, showing the device in position. Fig. 3 is a view simi lar toFig. 1, showing a double-tongue strip. Fig. 4 is a view similar to Fig.2, showing the application of the double-tongue strip. Fig. 5 is asectional view showing the tongues somewhat wider apart. Fig. 6 isaperspective view showing a reinforced tongue. Fig. 7 is a sectionalview showing the reinforced tongue en aging the groove of the sash. Fig.8 is a simi a'r view showing the single rib engaging an inserted plowmember set in the sash. Fi 9. is a sectional detail view'showing asim'ar interfitting member located between the tongues. Fig. 10 is a similarView showing a redoubled plow member engaging the double tongues. Figs.11 and 12 are detail views showing tongues having turned and roundededges, respectively.

My invention relates to improvements in metallic weather-strips of theclass wherein a projecting ton us or rib is arranged to interfit andmake s iding engagement with a corresponding receiving groove or plowmember so as to provide a sealing-joint'for the urpose of preventing thepassage of air, ust, moisture, &c., in whatever position the window orother element to which the device is ap lied may assume in the frame.

the accompanying drawings I have illustrated several forms of theinvention, which consists, generally, of a primary base 4 ofsubstantially the width of the runway, a reflexed secondary base 3, anda projecting tongue or rib 2, bent outwardly at about a right angle fromthe secondary base 3, all of such parts being made of one sheet foldedor bent, asclearly shown. In Fig. 3 the device is shown as provided withdouble separated ribs 2 2, such construction bein merely a duplicationof that already descri ed and as shown in Fig. 1. In both constructionsthe strip is secured against the base of the runway of'the sash-frame bymeans of tacks or nails 5, driven through the base 4 at intervals, and,as shown in the drawings, these attaching devices are located either toone side of the sin le rib, as in Fig. 2, or between the separate doubleribs, as in Fig. 4. In both such attachments. it will be observed thatthe base 4, the secondary base 3, and the rib 2 require no othersecuring attachment except such tacks or nails, and that these portionsare therefore somewhat free to move outwardly or inwardly, or that therib may be deflected laterally to a considerable degree withoutdisturbin the attachment to the frame. This flexibi ity is ofconsiderable advantagein allowing the rib or ribs to make a tight bindinfit with the groove in the sash-frame, an particularly with thedouble-rib construction they may be originally fitted somewhat tightlyin the groove and will bear outwardl at each side, retaining theirelasticity, an thus insuring a tight weather-proof closure at all times.

The ribs 2 2 may be located at any desired distance apart, and in Fig. 5I have shown them separated sufiiciently far to ro'vide for clearance ofthe sash-cord, in whic construction the ribs may engage a single widegroove or may each enter its own appropriate single groove in the sash.

In Fig. 10 I have shown the form of strip illustrated in Figs. 3 and 4,but with an interfitting tongue member formed of a separate strip ofmetal bent in W form, so as to provide a central rib 6 and sides 7 7,arranged to fit between and embrace the tongues 2,-as will be readilyunderstood. This supplemental tongue member is similar inconstruction tothe tongue member shown in my prior patent, dated November 4, 1902, No.712,761.

In Figs. 8 and 9 are shown supplemental interfittmg U-shaped stripsformed of doubled sides secured to the edge of the sash by nails andadapted to embrace the tongue 2, as in Fig. 8, or to be embraced bythem, as in Fig. 9. In either construction a tight interfitting engaement is secured.

In Figs. 6 and 7 I have shown a further with a supplemental attachedreinforced edge 8 consisting ,of a separate strip of metal bent in Uform embracing the projecting rib and secured to it in any suitablemanner, as by pressing it tightly together to clamp it thereto or bypartial riveting operation, as by a series of indentations 9. The strip8 might modification, wherein the rib 2 is provided IIO also be solderedor actually riveted to the rib. The object of this construction is tothicken theprojecting rib or tongue, increasing its body portion, andalso providing a rounded edge, giving a more finished smooth exterlorpro ecting portion.

In Figs. 11 and 12 the tongues are shown turned over, either at rightangles, as at 10, or reflexed uponitself, as at 11, so as to form afinishing or thickening head. This conprovided with a runway, of a metalweatherstruction not only strengthens the tongues, but also gives them arounded smooth edge.

The advanta es of my improved weatherstrip will be fu ly appreciated byall-"those familiar with this art, as it provides a very simple,inexpensive device, well adapted to the objects in view," providingconsiderable elasticity to compensate for any inequalities due to warpae or shrinka e, while requirin no especial skill to install. Thepreferre I material of which my strip is made is sheetzinc, although Ima employ other noncorrosive material. heet-zinc, while possessing alimited degree of elasticity is preferable on account of itsflexibility, ease of working, and non-corrosive qualities, while theterminal tongue or rib will maintain sliding engagement with the grooveof the sash independent of variations in alinement due to warpage orshrinkage, and it will be understood that in making the strips thesecondary base-flange 3 may be extended outwardly somewhat at an angleto the base 4, so that when pressed back against such base it will bearoutwardly against the, edge of the sash with considerable binding force,thus increasing its efficiency.

It will be understood that the strip may be made in various sizes orwidths and that changes or modifications may be made in its specihcdetails by the skilled mechanic without departing from the scope of thefollowing claims.

What I claim is 1. A metallic weather-strip com osed of a primary fiatbase of suitable metall bent inwardly upon itself at each side to formsecondary bases, the terminal edge portions of said secondary basesbeing bent outwardly: at right angles and adapted to engage a groove inthe edge of a window-sash, sub

stantially as set forth.

2. a weather-strip, the combination ofa primary base of sheet metal andsimilar secondary bases attached thereto having their terminal edgeportions bent outwardly at right angles and adapted to engage a groovein the edge of a \V'lIldOW-S&S' h,Sllbstantially as set forth.

3. The combination with a window-frame strip composed of a prima basesecured in the runway and areflexe secondary base' having a flangeextending angularlytherefrom, said secondary base and its flange beingcapable of movement relatively to the primary base and a window-sashprovided with a groove in its edge with which said flange slidablyengages; substantially as described.

4. The combination with a sash provided with a receiving-groove, of astationary frame member composed of a primary base of suitable metalbent inwardly upon itself at each side to form secondary bases, theterminal ed e portions of said secondary bases being Tm and extendinginto the groove of the windowsash, substantially as set forth.

I 5. The combination with a weather-strip formed of sheet metal bentorfolded inwardly at each edge and extending outwardly to form terminalprojecting ribs; of a movable member secured to the sash and ininterfitting enga ement with said ribs, substantially as set orth.

6. The combination with a weather-strip formed of sheet metal bentor-folded inwardly at each edgeto provide secondary bases terminatin inoutwardly-extendedribs, of an independent resilient tongue member formednt outwardly at right angles of a U-shaped strip secured to the sash andI embraced by said ribs, substantially as set v forth. In testimonywhereof I afiix my signature in presence of two witnesses.
